Platform Architecture

One platform.
Every business workflow.

Lowco is a set of shared services — identity, data, APIs, workflows, and a visual builder — composed into the apps you use today and the apps you'll build tomorrow.

Client · Web · Mobile · API consumers

Lowco API Gateway

auth · routing · rate limits · observability

Workflow Engine

triggers · steps · retries · AI actions

Studio Runtime

visual apps · code blocks · environments

Service Mesh

CRM · HR · Engage · Invoicing · Tasks

Lowco Auth

users · orgs · RBAC · SSO · SCIM

Lowco DB

relational + analytical · branches · RLS · CDC

Audit log · Event stream · Observability

Every Lowco product enters through the same Gateway, leans on the same Auth and DB primitives, and emits to the same event stream. The diagram is the architecture.

Architecture

Built for the operating model of a real company.

The platform is opinionated where it matters and pluggable where it doesn't.

Shared identity

Every product reads from one identity model. Users, organizations, roles, and policies live in Lowco Auth — and apps consume them through the same SDK.

  • SAML, OIDC, SCIM, passkeys
  • Org-aware tokens with short TTLs
  • RBAC enforced at the storage layer

Unified data layer

Lowco DB is a relational + analytical engine. Every product writes to it, every product reads from it — without the export-to-warehouse detour.

  • Postgres-compatible interface
  • Row-level policies driven by Auth
  • Branch-based environments

Edge gateway

The Gateway is the single entry point for every API. It does auth, rate limits, transformation, and observability so your services don't have to.

  • Versioning per consumer
  • OpenAPI / GraphQL schemas
  • OpenTelemetry pass-through

Event-driven core

Everything that happens — a record changing, a user signing in, an agent finishing — is an event on the same stream. Workflows subscribe; products react.

  • At-least-once delivery
  • Replay across time windows
  • Strongly-typed schemas

Automation & agent runtime

The workflow engine and agent runtime share one execution model. Steps can be code, API calls, or AI actions — all observable, all retryable.

  • Deterministic state machine
  • Per-step timeouts and retries
  • Audit trail per execution

App builder architecture

Studio compiles to a typed React app backed by Lowco services. Code blocks are first-class — escape the canvas without leaving the platform.

  • Typed schemas across UI and DB
  • Code blocks in TypeScript and SQL
  • Branches, environments, publishing
Developer experience

The platform you'd build, if you had the time.

Lowco gives you the primitives that make backends fun again — typed APIs, clean SDKs, branch-based environments, and observability you don't have to wire up.

  • Typed SDKs in TypeScript with first-class server actions.
  • Branch-based environments for DB, Studio apps, and configs.
  • Per-endpoint metrics, traces, and replay-by-request-id.
  • Local dev with a single CLI — no Docker required.
  • Multi-region deploys with zero-downtime cutovers.
  • One model from data → API → UI — no integration glue.
create-customer.ts
import { lowco } from "@lowco/sdk";

export async function createCustomer(input: NewCustomer) {
  const { user, org } = await lowco.auth.requireOrg();

  const customer = await lowco.db("customers").insert({
    org_id: org.id,
    name: input.name,
    email: input.email,
    owner: user.id,
  }).returning();

  await lowco.engage.sendJourney("customer_welcome", {
    user_id: customer.id,
    properties: { plan: input.plan },
  });

  await lowco.events.emit("customer.created", customer);
  return customer;
}
Enterprise & Security

Built for the controls IT requires.

Lowco was built with enterprise from day one — not retrofitted later. Identity, audit, isolation, and observability are first-class across every product.

RBAC

Role and attribute-based access, inherited across every product.

SSO

SAML 2.0, OIDC, and SCIM provisioning for enterprise IT.

Audit logs

Tamper-evident logs for every auth, data, and config change.

Multi-tenancy

Hard isolation per project, with optional dedicated infrastructure.

API observability

Latency, error rates, traces, and replays per endpoint.

Security-first

Threat modeled, encrypted in transit and at rest, signed builds.

Scalable infrastructure

Horizontally scaled services across multiple regions.

Cloud-native design

Built on managed primitives — no servers for you to mind.
